Factors affecting intraspecific diet variation of ducklings: Niche partitioning in a heterogeneous landscape?

open access: yesEcosphere, Volume 16, Issue 12, December 2025.
Abstract Variability in resource use within populations of free‐ranging animals can influence demographic and evolutionary processes. Yet in many ecological systems, the extent of intra‐population variation in the resources that animals consume and the environmental factors that contribute to this variance remain poorly understood. For example, dietary

Far From Roads, Challenges Arise: Unravelling Knowledge Gaps in the Occurrence of Cave‐Restricted Species on the African Continent

open access: yesAfrican Journal of Ecology, Volume 63, Issue 8, December 2025.
ABSTRACT Understanding patterns of biodiversity distribution is fundamental for ecology, biogeography, and conservation. However, persistent challenges arise from the inaccessibility of many regions and habitats. Subterranean environments, in particular, host highly distinctive and specialised faunal assemblages, yet their investigation is hindered by ...

Shore crabs reveal novel evolutionary attributes of the mushroom body

open access: yeseLife, 2021
Neural organization of mushroom bodies is largely consistent across insects, whereas the ancestral ground pattern diverges broadly across crustacean lineages resulting in successive loss of columns and the acquisition of domed centers retaining ancestral

Measuring juvenile habitat quality for fishes and invertebrates

open access: yesBiological Reviews, Volume 100, Issue 6, Page 2346-2395, December 2025.
ABSTRACT Identifying the role of marine and estuarine habitats in supporting fish and invertebrate populations during vulnerable juvenile life stages is essential to achieve effective conservation and fisheries management. There remains general agreement that: (i) the quality of juvenile habitat is best measured as the contribution of juveniles to ...
